Sorry if that has been posted before, but I really tried searching and couldn't find exactly what I was looking for. I am thinking of trying my hand at strap making and have started to order the tools online. I've managed to find most of the things I require, but am a little unsure of the thickness of the waxed thread used. I'm looking to work on mostly 20-24mm straps and can't figure out what the thickness of there thread should be. I found an old post where someone suggested a 4 or 5 ply thread, but the place where I'm looking to buy from has the thickness mentioned in millimetres, like .6mm or 1mm.
Could someone here please enlighten me on what to go for?
